The blog had been out-earning my salary by a significant margin for a while and it had reached a point where I felt I had to devote my full time.

How did I convince myself that leaving a good, stable, growing career for an unpredictable future with an untested business model was a good idea?

I bought myself time.

The first year of the site, it earned about $3,000. The year I quit my job, a few years later, it was 4-5X my annual salary.

The way I figured it, the business had bought me 4-5 years. Each subsequent year bought me even more runway and, if I was fortunate, I could grow the business and the runway would lengthen even more. I could quit my job to do work on the business because I had saved enough income to pursue it full time.
